Sync Stones are the item Global AION 2 players can't find. NC's 11 November patch added a weekly mission that pays three, and hours later an r/Aion2 post was still titled About to quit because of sync, its IMPOSSIBLE to get combat speed. This guide lists every Sync Stone source the Global client has as of 12 November 2026, after the 11 November (CET) patch, how many Syncs a good line really takes, and why Korea's numbers aren't a fair comparison.
Quick answer: On Global you get Sync Stones from 3 places. The new weekly Season Mission Way of the Transcended Steps pays 1 Sync Stone (Unique) (Bound) per step, up to 3 a week, for Transcendence clears. Substance Morph turns a Gear Change Voucher: Krao Cave (Bound) into one, and client data lists that voucher as a guaranteed Krao Cave reward after 14 and 28 reward claims. And 12 Sync Stone Fragments plus 100,000 Kina morph into one stone, though fragments have almost no Global source right now. A spare Unique item also works as Sync material, and it's still the main way to Sync on Global.

What is a Sync Stone in AION 2?
A Sync Stone is the material for the Sync button in Soul Binding. Sync rerolls one Soul Binding line you pick and keeps the others. The item text in the Global client says it "harmonizes the energies within gear" and that, used in Enhancement > Soul Binding > Sync, "it allows you to adjust the properties of gear."
Three things about the item matter before you plan around it:
- It's Bound and can't be traded. Game8's item page marks it character storage only, with no server storage and no public or personal trade. You can't buy it on the Market, and nobody can sell you one.
- It's not the only Sync material. Sync also accepts a Unique item. Our Soul Binding guide covers the window: a Unique item on Unique gear shows a 100% Success Chance, which means the swap happens, not that you get the line you want.
- It stacks to 1,000 and is item level 84, per MetaBot's client read.
So a Sync Stone saves you a Unique item. That matters because Unique gear is also what you wear, Transfer and enhance, and some players have reported fewer of them dropping since the 4 November patch.
How do you get Sync Stones in AION 2 now?
Here is every Global source we could verify, from the most reliable down.
| Source | Sync Stones | Limit | Status on Global |
|---|---|---|---|
| Way of the Transcended Steps (Season Mission) | 1 per step, 3 steps | Up to 3 a week | Live since 11 Nov 2026 (NC notes) |
| Substance Morph: Gear Change Voucher: Krao Cave (Bound) | 1 per voucher | Voucher guaranteed after 14 and 28 Krao Cave reward claims (client data) | Recipe in client data (Wikily) |
| Substance Morph: 12 Sync Stone Fragments + 100,000 Kina | 1 | Limited by fragments | Recipe exists, fragment sources missing |
| Daeva Pass | 0 on the Season 1 track | 101 levels | None listed |
| Ludra, Hard Expedition cubes, shops | 0 | n/a | None in the Global reward lists |
The weekly mission: Way of the Transcended Steps
This is the new source, and the only one NC has written down. The 11 November patch notes say:
"Sync Stone rewards (up to 3 per week) will be added to the weekly Season Missions for Transcendence Dungeons." (NC patch notes, 11 November 2026)
The mission is Way of the Transcended Steps, Steps 1 to 3, and NC says "1 Sync Stone (Unique) (Bound) will be awarded for each mission." NC doesn't print how many clears each step needs. Players report that Step 3 tracks 10 Transcendence clears, and one r/Aion2 thread worked out that all three stones take 10 clears and 400 Odyle Energy. Replies in the same thread say a clear counts even if you don't open the cube. Treat both as player reports until NC confirms them.
If you do open every cube, at 40 energy each, 10 clears cost 400 energy. Recharge gives about 840 a week according to client trackers, so that's roughly half your weekly bar. Our Odyle Energy guide has the full budget, and the Transcendence guide covers which dungeons count.
Do the three steps every week before anything else that spends energy. It's a weekly Season Mission, so finish it before the weekly reset, which client trackers put at Wednesday 07:00 UTC (Tuesday night in North America).
The Krao Cave voucher
Client data has a Substance Morph recipe that turns 1 Gear Change Voucher: Krao Cave (Bound) into 1 Sync Stone (Unique) (Bound), per Wikily's client data. MetaBot's item page says the voucher is "a reward obtained by defeating Ultimate Berk" and lists it as a guaranteed Krao Cave reward after 14 and after 28 reward claims. Guaranteed rewards count cube claims, not entries.
The catch is that the same voucher also morphs into a Unique Gear Selection Chest. You have to choose. If you're still missing Unique slots, the chest is usually worth more. If your gear is set and you're fishing for one line, take the Sync Stone.
Sync Stone Fragments
Game8 lists the fragment recipe: 12 Sync Stone Fragments and 100,000 Kina make one Sync Stone. The problem is the fragments. MetaBot's client read lists only "Battle pass" as a fragment source, and the Season 1 Daeva Pass track it publishes, all 101 levels, has no Sync Stone or fragment on it. Players reported on 7 November that Sync Stone and fragment sources from launch had disappeared, and NC hasn't explained it in writing.
What doesn't give Sync Stones on Global
- Ludra. The 11 November patch raised Ludra's Reward Group 5 from a 30% to a 100% drop chance and added Wrathful Mind, Will and Ego. No Sync Stone.
- Hard Expeditions. The new Fire Temple and Ferocious Horn Den Hard rewards are Philosopher's Stone: Revelation, Ariel Fragments and Unique crafting materials. NC's 20 October Hard list had no Sync Stones either.
- Shops and the Market. MetaBot says the Global client "names no monster drop, dungeon, quest, shop or recipe" for the stone beyond its pass and conversion entries. It can't be traded, so the Market is out.
How many Sync Stones do you actually need?
More than three a week covers. Sync picks a new line at random, so the number depends on how rare your target line is. These per-roll chances come from Game8's Soul Binding table and AION 2 Tier List's client read. NC hasn't published odds, so read them as community data.
| Target line | Slot | Chance per Sync | Average Syncs | Weeks at 3 a week |
|---|---|---|---|---|
| Multi-hit Chance | Weapon / guard | 4.8% | about 21 | about 7 |
| Combat Speed | Weapon / guard | 3.2% | about 31 | about 10 |
| Weapon Damage Boost | Weapon / guard | 3.2% | about 31 | about 10 |
| Combat Speed | Gloves | 2.4% | about 42 | about 14 |
| Damage Boost | Weapon / guard | 1.6% | about 63 | about 21 |
"Average Syncs" is 1 divided by the chance. Luck spreads it wide: at 3.2%, about half of players hit within roughly 22 Syncs, while the unlucky tail runs past 60. Sources also say the odds may shift with the lines already on the item.
That is why the "impossible to get combat speed" post struck a nerve. Its screenshot, shown at the top of this page, is a +15 Unique greatsword with Weapon Damage Boost, Damage Boost and Multi-hit Chance, which is a strong weapon, and no Combat Speed.
Chasing Combat Speed on that weapon with Sync Stones alone would take around ten weeks at the new rate. Season 1 ends at the 16 December (CET) maintenance, which leaves five weekly cycles counting patch week, so about 15 Sync Stones this season at most from the mission.
The honest conclusion: Sync Stones are a top-up. Unique gear is still your real Sync material.
How can you get more Syncs from what you already have?
- Clear all three Transcended Steps every week. It's 3 free Syncs and the only guaranteed source.
- Sync with spare Unique gear first. Every Unique you'd otherwise Extract is a free Sync. Keep the duplicates from Conquest and Expedition cubes until your main pieces are done.
- Spend Sync Stones only on your last missing line. A stone and a Unique item do the same job, so save the stones for the piece you'll keep longest, usually the weapon.
- Roll cheap pieces, then Transfer. Our Soul Binding guide explains the route: roll lines on low item level Uniques, keep the one with a rare line, and move it with Transfer. The gear transfer guide covers the limits.
- Decide each Krao Cave voucher on purpose. Chest if you're missing a Unique slot, Sync Stone if you're not.
- Don't Reset a piece that already has one good line. Reset rerolls everything for 300,000 Kina and 3 Soul Codex: Reset. Sync keeps what you have.

Why does Korea get more Sync Stones than Global?
This is the comparison the subreddit keeps making, and part of it is fair.
What Korea got. NC's Korean update of 17 December 2025, reported by Game Chosun, added Sync Stone Fragments to Hard cubes, a Sync Stone as a selectable guaranteed Hard reward, 4 Sync Stones per Ludra kill, and the 12-fragment morph. Global's 20 October Hard list and 4 November Ludra list had none of those.
Why the gap is smaller than it looks. A widely shared r/Aion2 explainer and its replies point out that Korea had no gear Transfer in its first season. Every new piece had to be rerolled from zero, so Korea needed far more stones. On Global you roll a line once and carry it forward. That's a player account, not an NC statement, but it matches how Transfer works here.
Korea is now getting fewer. Players translating Korea's 11 November 2026 notes report that the update reduces Sync Stones (Unique) obtained in the Sanctuary and cuts some Unique gear drops. We couldn't confirm the exact wording from an English NC source, so treat it as community translation.
What's still a real gap. Global players are also fighting a Ludra that needs far more combat power than Korea's version did, according to the same threads. More gear pressure and fewer stones is why three a week feels small. Our Ludra raid guide has the current gates.
Will NC add more Sync Stones?
NC hasn't said. The 11 November notes call the mission one of the "rewards needed for character progression" added to weekly content, which reads like a first step, not a ceiling.
Two things to watch. Season 1 ends at the 16 December (CET) maintenance, and NC hasn't announced what Season 2 brings. Korea's own Sync sources grew over its first year, and its December 2025 changes came about a month after launch, which players describe as a response to complaints. Global is now around six weeks in. If more sources land, they're most likely to show up in a Tuesday or Wednesday patch note, and we'll update this page and our patch notes tracker when they do.
FAQ
How do I get Sync Stones in AION 2? Clear the weekly Way of the Transcended Steps mission for up to 3 a week, morph a Gear Change Voucher: Krao Cave into one at Substance Morph, or morph 12 Sync Stone Fragments with 100,000 Kina. A spare Unique item also works as Sync material.
How many Sync Stones can you get per week? Three from the Transcendence mission, according to NC's 11 November 2026 patch notes. Krao Cave vouchers can add one each, but client data guarantees them only after 14 and 28 reward claims.
Can you buy Sync Stones in AION 2? No. They're Bound, so they can't go on the Market or be traded, and no Global shop lists them. Nobody can sell you one.
Does Ludra drop Sync Stones on Global? No. The 11 November patch improved Ludra's Reward Group 5 with Wrathful Mind, Will and Ego, but no Sync Stone. Korea's Ludra paid 4 per kill from December 2025.
Is a Sync Stone better than using a Unique item? They do the same job in the Sync window. Use spare Unique gear first and save Sync Stones for the piece you'll keep longest.
How many Syncs does Combat Speed take? About 31 on average on a weapon or guard, at a reported 3.2% per roll, and about 42 on gloves at 2.4%. NC hasn't published Soul Binding odds.
The bottom line
Three Sync Stones a week won't finish a weapon, and it isn't meant to replace Unique gear as material. Clear Way of the Transcended Steps every week, Sync with every spare Unique before you Extract it, spend stones on your last missing line, and pick the Krao Cave voucher's reward on purpose. If you're chasing Combat Speed, plan for weeks, not days.
